    Dear All,

    I have a partition need to backup (for example, /dev/hda4) How can I backup it with afbackup? and how can I restore it (for example, restore to /dev/hd5).

    Thanks a lot.

      I found that it can backup by:
      afbackup -cv /..//dev/hda3

      However, when I try to restore:
      afrestore -a

      The status report: "waiting for space in read buffer" and the restoration hanged. Any idea?

      Thx.
      Alex

      I can restore the data now. However, the restore speed is very slow (around 24KB/s). How come? Who can help me?
